  • the present invention enables users to open or lock the connecting lock 300 from the back and the front of the lamp board 110 respectively, which facilitates the disassembly and assembly.
  • the LED display module units 100 are spliced to form an integrated LED display screen, if the integrated LED display screen is against the wall, the gap between the integrated LED display screen and the wall is often small. In this case, the user can not reach the back of the integrated LED display. At this time, the user can open the connecting lock 300 through the front opening structure 320 in front of the lamp board 110, which can greatly improve the efficiency and convenience of disassembly and assembly.
  • the connecting lock 300 includes a rotating shaft 330 and a locking structure 340.
  • the locking structure 340 is fixedly connected to the rotating shaft 330, and the locking structure 340 can rotate synchronously with the rotating shaft 330.
  • the locking structure 340 is an elastic ring rod.
  • the rear opening structure 310 is provided at the rear end of the rotating shaft 330, while the front opening structure 320 is provided at the front end.
  • the rear opening structure 310 is a rotary button.
  • the front opening structure 320 is a hexagon socket.
  • the user can manually turn the rotary button to make the locking structure 340 and the rotating shaft 330 rotate synchronously, so as to open or lock the connecting lock 300, when the locking structure 340 rotates and is stuck on the splicing frame 200, the LED display module unit 100 can be assembled in the splicing frame 200.
  • the user can insert the front opening tool 321 into the hexagonal rotating rod and rotate it to make the locking structure 340 and the rotating shaft 330 rotate synchronously so as to open or lock the connecting lock 300.
  • the front opening structure 320 is hidden and embedded in the lamp board 110 to achieve the purpose of not blocking the image displaying.
  • a plurality of connecting locks 300 may be provided around the lamp board 110 to ensure a safe connection.
